I'm trying hard to develop an application in Zope and I'm crashing against 
brick walls in every step.
It seems I still don't get the philosophy of Zope/web application development.
How do I know what objects exists when a script I wrote run, and what classes 
those objects belong to and what methods does classes have... that is, the 
functionality I have. In php I just had a bunch of variables printable by 
phpinfo() and/or print_r (a print all command) to inspect structures and so 
on... dir() doesn't work in zope, so, I don't have the standard python way of 
doing this.
My current questions are:
1) How do I get my username and related information ?
2) How do I add more methadata to users, like name and e-mail ?
3) How do I list folders that are owned by the logged in user ?
4) How do I redirect the browser to another page ?
Thanks.
